Hi, I managed to get my arrays working thanks to the people who helped me with that. However now I have a new problem from some reason the receiving unit is not receiving any data I am not sure what I'm doing wrong. What I am trying to do is take data from the TX unit and transfer it to the RX unit. The TX unit takes data from a 4x4 keypad which is then stored within a string or an array and then transfered by pressing the enter key or key 15.
In the attached files one is the TX unit and the other is the RX unit code I have also included my Serin2 which will not work.
